Bacopa monnieri (Coastal Waterhyssop, Brahmi, Thyme-leafed gratiola, Water hyssop) is a perennial, creeping herb whose habitat includes wetlands and muddy shores. Brahmi is also the name given to Centella asiatica by some botanists, while others consider that to be a mistake that arose during the 16th century, when brahmi was confused with mandukaparni, a name for C. asiatica.
The leaves of this plant are succulent and relatively thick. Leaves are oblanceolate and are arranged oppositely on the stem. The flowers are small and white, with four or five petals. Its ability to grow in water makes it a popular aquarium plant. It can even grow in slightly brackish conditions. Propagation is often achieved through cuttings.
It commonly grows in marshy areas throughout India, Nepal, Sri Lanka, China, Taiwan, and Vietnam, and is also found in Florida and other southern states of the USA where it can be grown in damp conditions by the pond or bog garden.
This plant has a number of uses in Ayurveda. It is a traditional treatment for epilepsy and asthma. It has antioxidant properties, reducing oxidation of fats in the bloodstream. Studies in humans show that an extract of the plant has antianxiety effects.
It is listed as a nootropic, a drug that enhances cognitive ability. In India, this plant has also been used traditionally to consecrate newborn babies in the belief that it will open the gateway of intelligence. Laboratory studies on rats indicate that extracts of the plant improve memory capacity and motor learning ability. Recent studies suggest bacopa may improve intellectual activity. In a double-blind, placebo-controlled randomized trial, human subjects taking an extract of Bacopa monniera showed significantly improved performance on tests for spatial working memory and rapid visual information processing. The sulfhydryl and polyphenol components of Bacopa monniera extract have also been shown to impact the oxidative stress cascade by scavenging reactive oxygen species, inhibiting lipoxygenase activity and reducing divalent metals. This mechanism of action may explain the effect of Bacopa monniera extract in reducing beta-amyloid deposits in mice with Alzheimer's disease.
A standardized Bacopa monniera preparation was evaluated for safety and tolerability in 23 healthy adult volunteers. Participants took 300 mg of the extract daily for 15 days, followed by 450 mg/daily for the subsequent 15 days. No adverse effects were observed in biochemical, electrocardiographic, hematological or clinical parameters in the post-treatment vs. the pre-treatment period. There were some reports of mild gastrointestinal symptoms that resolved spontaneously.

It seems that this identification of brāhmī as C. asiatica has been in use for long in northern India, as Hēmādri's 'Commentary on Aṣṭāṅgahṛdayaṃ (Āyuṛvēdarasāyanaṃ) treats maṇḍūkapaṛṇī (C. asiatica) as a synonym of brahmi."
